Twenty four Hanwoo steers(average body weight=550.4±42.8kg) were used in the experiment to determine the effects of supplementing coated vitamin C+E with cottonseed on meat quality, meat color and carcass grade in Hanwoo steers fed brewers grain and cracked corn-based fermented feedstuff. Steers were randomly assigned to feeding groups of fermented feedstuff without any supplements(T1) and fermented feedstuff supplemented with coated vitamin C+E and cottonseed(T2). Ether extract content of longissimus dorsi was higher in T2 than in T1(p<0.05). Yellowness and hue-angle among surface colors of longissimus dorsi was lower(p<0.05) in T2 than in T1 but lightness was higher(p<0.05) in T2 than in T1. Ratio of yield grade ‘A’ was higher from T2 group than from T1 group. Marbling score was higher in T2 than in T1(p<0.05). Present results indicate that supplementation of coated vitamin C+E and cottonseed to brewers grain and cracked corn-based fermented feedstuff has positive effects on ether extract content, color, marbling score of longissimus dorsi in Hanwoo steers.
